Justification of rational parameters of prospective technological schemes of layer mining of thick polohugol beds

Article preview

Выполнен анализ перспективных технологических схем слоевой отработки мощных пологих пластов Кузбасса. Сделан вывод о необходимости учета при определении предельной мощности межслоевой угольной пачки влияния «надработки» 2-го слоя. Выполнены аналитические исследования напряженно-деформированного состояния «надработанного» массива. Установлены размеры зон разупрочненного угля и даны рекомендации по определению предельной мощности защитной пачки.

Increase of technical and economic indicators of layer mining of thick hollow seams of Kuznetsk coal basin

Article preview

The know-how of layer improvement of thick hollow seams in the mines of Kuzbass is analyzed. The conclusion is made about the necessity of subcladding justification of the location of local development workings of layer 2, providing the minimization of costs for their development and maintenance. The influence of mining engineering factors on the stress-strain state of rock massif in the vicinity of layer 2 layer workings has been investigated. Recommendations on the choice of rational location of local development workings are made. The economic benefit from the implementation of the developed recommendations is estimated.

Justification of rational parameters of perspective technological schemes of layer mining of thick hollow coal seams

Article preview

Perspective technological schemes of layer mining of thick gentle seams of Kuzbass are analyzed. It is concluded that it is necessary to take into account the influence of the 2nd layer overworking when determining the ultimate capacity of the interlayer coal bundle. Analytical studies of stress-strain state of the overworked massif have been carried out. The dimensions of the zones of unstrengthened coal have been determined and recommendations for determining the ultimate thickness of the protective bundle have been given.
